Title: Working method for negative pressure floating head slider
Inventor: HORI AKIO
IPC: G11B5/60
Filed: 1985-03-07
Abstract: PURPOSE:To work a negative pressure floating head slider to required working precision quickly and inexpensively by working a parallel plane by the dry etching method and working an inverted taper part by grinding. CONSTITUTION:The most important dimensions of the negative pressure floating head slider are a recess depth H1 in the air inflow end and a recess depth H2 in the air outflow end, and it is necessary to work them with high precision, and normally, the recess depth H1 is set to <=5mum, and the recess depth H2 is set to >=5mum and <=50mum. In this case, a parallel plane 7 is worked by what is called the dry etching method like the ion beam etching method, the sputter- etching method, or the plasma etching method. Meanwhile, an inverted taper surface 8 is worked by conventional grinding.

Title: Output circuit
Inventor: ISHII KAZUSANE
IPC: H03K17/16
Filed: 1992-03-03
Abstract: PURPOSE:To prevent a through-current of an output stage of the output circuit by preventing that transistors(TRs) being components of an output stage of the output circuit are simultaneously turned on. CONSTITUTION:A transistor(TR) Q1 whose base electrode is open is added newly to an output circuit 100a. When a current fed from the circuit 100a to an inductor load L is inverted, parasitic TRs QK1, QK2 are conductive, then a base current of the TR Q1 is drawn and the TR Q1 is turned on. A current is supplies from a collector electrode of the TR Q1 is supplied to a base electrode of the TR Q2. Then a base current of the TR Q2 is not drawn and the TRs Q2, Q3 are turned off. Since the TRQ3 is turned off when the TR Q4 is turned on, a through-current between the TRs Q3, Q4 is prevented.

Title: Production of highly electroconductive polymer composition
Inventor: NAITOU KAZUMI
IPC: C08F291/00
Filed: 1983-03-22
Abstract: PURPOSE:To obtain the titled uniform brittleness-free composition, by polymerizing an acetylene compound in the presence of thermoplastic polymer powder. CONSTITUTION:An acetylene compound (e.g., acetylene, phenylacetylene or methylacetylene) is polymerized in the presence of thermo-plastic polymer powder, e.g., PE, PP, polyamide, polyester, or a mixture thereof with an electroconductive material such as carbon black. Conventional acetylene high polymer is unsatisfactory in moldability because of its insolubility and infusibility and therefore it must be cold-worked. Nevertheless, the molding has suffered from inherent brittleness because bonding among the particles is poor. It becomes possible to obtain an extremely uniform polymer composition free from brittleness by carrying out the polymerization in the presence of the thermoplastic polymer powder, and the resulting polymer composition can be used very satisfactorily as a material for solar, primary or secondary batteries, or a photoconductive material.

Abstract: PURPOSE:To obtain a hard mirror having a dead slender scope which is capable of obtaining a normal and distinct observation image, by providing a deleterious light eliminating part on a part of an optical path of the scope which is used both as an observing optical system and an illuminating optical system. CONSTITUTION:Light emitted from an illuminating light source 18 passes through a light guide 17 and is made incident to a relay lens 7 at an incident angle of a prescribed range from the circumferential face of the relay lens 7. The incident light repeats its reflection by the circumferential face of the relay lens, whose outside circumference is covered with an air layer 10, is converged by an objective lens 10, is emitted from cover glass 8 and irradiates an object. The reflected light forms an image through the cover glass 8 and an objective lens 6. Its image forming light is propagated in the relay lens 7, passes through an area of a light absorbing member 11, forms an image on the rear end face of the relay lens 7, and goes into an observer's eye through an eyepiece 15. On the other hand, abnormal light passes through the air layer 10 at a larger angle than that of the image forming light, is made incident to the light absorbing member 11 and is absorbed. Accordingly, by the dead slender scope, a normal and distinct observation image is obtained.

A manager in a control center 80 receives abnormality information and detects that the presence mode is set, he confirms conditions by telephone because the speaking mode is already set. Thus, the system is obtained where the abnormality is quickly confirmed to prevent the extension of damage.
